This document contains notes from a chemistry laboratory class. It includes the chemical formulas for various compounds tested in a quiz, as well as sections on different types of chemical reactions like combination, decomposition, single displacement and double displacement reactions. Examples are provided for each type of reaction. Safety precautions for the laboratory are emphasized.

15. Introduction
Chemical changes
are called Chemical
Reaction. In
science, we write
the Chemical
Reaction in a form
of Chemical
Equation.

18. Combination Reaction
Also known as
synthesis reactions,
these are reactions in
which 2 or more
substances combine
to form a more
complex substance.

19. Combination Reaction
A+B
AB

20. Combination Reaction
Example:
C + O2
CO2

21. Decomposition Reaction
Is the reverse of
combination
reaction. In this
reaction, a complex
substance is broken
down into simpler
substances.

22. Decomposition Reaction
AB
A+B

23. Decomposition Reaction
Example:
2HgO 2Hg+O2

24. Single-Displacement Reaction
Are reactions in
which an element
displaces another
element that is in a
compound. It is also
known as
Substitution
Reaction.

25. Single-Displacement Reaction
A+BC
AC+ B
NOTE!!!

26. Note!!!
Refer to the activity series for
metals and non metals to
predict products of replacement
reactions. If the free element is
above the element to be
replaced, then the reaction will
occur. If it is below, then no
reaction occurs.

27. Single-displacement Reaction
Example:
Zn + 2HCl ZnCl2 + H2

28. Double-Displacement Reaction
Are reactions in
which two
compounds make an
exchange.

29. Double-Displacement Reaction
AB+CD
AD+CB

30. Double-displacement Reaction
Example:
BaCl2+ Na2SO4
BaSO4 + 2NaCl
